Count the number of times the string '?' occurs in variable line

Hi! How should I answer this question below? Any help is greatly appreciated!

Count the number of times the string '?' occurs in variable line. Choose any method that works reliably. Regardless of method, assume that a line won't consist entirely of '?'s.

Try and find a function here that will count the number of characters. 

The documentation has an example for the function towards the bottom of page.

Hint: You want to COUNT a character.

Hi @Amy0223 

You can use the countc() function for example:

var2 = countc(var1,'?');
